int to inet conversion - Mailing list pgsql-general

Dear All.
is there any function that can translate INT to INET type?
the table contains ip and mask in different fields (int fields):

  ip          | integer               | default 0
  mask        | integer               | default -1

db=> select ip, mask from ips limit 2;
      ip      | mask
-------------+------
  -1062726656 | -256
  -1062724096 | -256

But i need inet or sidr records :)

Best regards,
Anton
